Drew,

There are a couple of photos in the Rigging photo album.

The one in the link below is a common one which is probably the same as the Nacra.

Lock it off at the top of the mast. Locking at the bottom would just add too much stretch in the halyard and prevent you from getting the most out of the downhaul system.
